The attributes of the Ok Tedi SAG mills . that are used by the expert system are power draw lift pressure motor temperature and recycle tonnage. Fresh feed tonnage and feed density are the manipulated variables. Set point changes in tonnage or SAG mill feed density are returned to the DCS PID controllers. Fuzzy sets are defined for all the
SAG Mill power draw models are used in mill design and grinding circuit modelling to predict how much power will be consumed by a particular mill geometry and operating configuration. This paper will compare SAG mill models by Morrell Loveday using Power Numbers published by Barratt and Austin against several published mill surveys.
